Design and build backend services in Golang that integrate with payment processors, gateways, and card networks
Own critical money-movement flows end to end: authorization, capture, settlement, refunds, reconciliation, and chargeback/dispute handling
Build idempotent, fault-tolerant, auditable transaction processing within a distributed architecture (transactional outbox patterns; queues such as Kafka, SQS, or RabbitMQ)
Operate within PCI DSS scope — tokenization, network tokens, secure handling of payment data, and 3DS/SCA flows where applicable
Instrument and monitor payment health: authorization/decline rates, processor performance, latency, and settlement accuracy, driving continuous improvement
Use AI tooling (Claude and equivalent LLMs) as part of your daily workflow to accelerate design, coding, research, testing, and documentation — within Sezzle's security and data-handling policies
Mentor engineers and help raise the bar across the team.

7+ years of backend or full-stack engineering experience, with meaningful time spent on payments, fintech, or money-movement systems
Strong Go (preferred), or comparable experience in Python, building and serving REST APIs
Hands-on experience integrating with payment processors, gateways, or acquiring systems, and familiarity with payments fundamentals: authorization vs. settlement, tokenization, idempotency, reconciliation, and chargebacks/disputes
Experience in distributed, cloud-based architectures using patterns like transactional outboxes or queuing tools (Kafka, SQS, RabbitMQ)
Demonstrated, hands-on use of Claude or an equivalent LLM to enhance productivity, research, and communication — you're comfortable making AI a core part of how you work and can show how it's improved your output
